installed top row of Skybol cowling flanges. The hardest part is to figure out the spacing for the flanges. They suggest a 3 1/2 " spacing betweek fasteners but you have to space the fasteners so they end up properly lined up for the horizontal run along the cowling seam between top and bottom cowling halves. I started with one in the center. the next 6 at 3" spacing and then the next 2 at 3 1/2" spacing and the last one on the top cowliing at 2 1/2 ". This last one is now lined up with the horizontal run from back to front which go on with the bottom cowling half.
